Faulty electronic chip

This can be done by getting the key fob removed from its case, and using a needle or pin to make contact with each metal retaining clip. You will need to replace these when they're damaged or corrosion-prone. Make sure that the replacement batteries have the same size, voltage and specifications as the original.
